I wouldn't mind seeing a competitive candlekin deck. I saw @JeffHoogland playing a tri-shard one pre-CCS but it looked more of a fun deck than anything else. Since it's listed in your budget decks list, it means that at least some iteration is playable.

Massacre will be a bit conflict over Hailstorm, and also there are only 10 fateweave cards in this deck, so Hailstrom is not necessary in this deck , I suppose.

That's not a real conflict. If your Hawks are controlling the board you don't play massacre. If not you play massacre and just generate more hawks after that. Hailstorm seems too good to not include them.
